Question 1: Given the open-loop transfer function of a system with unit feedback, G(s) = (2s+1)/s2, determine the unit step response and unit impulse response of this system. Question 2: Given that the transfer function of the system is M(s) = 10/(0.5s + 1), determine the amplitude and phase of the steady-state output of the system under the action of a sinusoidal input signal with frequency f = 1 Hz and amplitude Ac = 10. (∏=3.14; tan-1=72.3°)
The original poster should take a look at the principles of self-control. The answer is too long, so I won’t go into the details of the reasoning.
The poster should pay close attention to the Laplace transform and Fourier transform, as well as the chapter on frequency domain analysis in the principles of automatic control
Don’t forget it all after 3 years; the length is too short
Examples from the textbook on control theory........................
Just flip through the textbook on automatic control principles and you’ll know
Flip through the textbook on control principles and simulate it again.
Take a look at the principles of self-control; over time, you won’t forget the formulas if you use them regularly
These types of interview questions are too disconnected from actual production in the field; they seem to be designed to test college students, rather than engineers. They also don’t represent any practical experience – it’s as if they’re meant to assess recently graduated college students, since these are questions that appear in university courses.
